Tailoring Sport Coats: Shortening Sleeves

Shortening the sleeves on a sports coat can make all the difference when it comes to fit and style. It's a relatively simple process if you have basic sewing skills and a sewing machine. First, you'll need to try on the jacket and decide where you want the sleeves to end, marking this spot with chalk. You'll then need to cut the sleeves, allowing for a seam allowance, before hemming the sleeves to finish them.

Try on the jacket to determine the new sleeve length

To determine the new sleeve length, start by trying on the jacket. Identify where you would like the sleeves to fall by bending your arms and holding them straight at your sides. Choose a midpoint measurement between these two spots. For example, if you want the sleeves to end at your wrist, but they are too short at this length when you bend your elbows, you might need to shorten them so they end about 0.5 cm below your wrists.

Mark the sleeves where you want them to end. To do this, use a piece of chalk to make a few marks around the sleeve, then connect these marks into a solid line. You may want to use a ruler to help you get a straight line and ensure that all the marks are the same distance from the end of the sleeve.

It's important to remember that the sleeve length affects the overall fit and appearance of the jacket. Sleeves that are too long or too short can make the jacket look ill-fitting and sloppy. Therefore, taking the time to accurately measure and mark the new sleeve length is crucial before proceeding with any alterations.

After marking the desired sleeve length, the next step is to measure and mark the hem allowance. This is necessary to ensure a neat finish and allow for future adjustments. Measure 2 inches (5.1 cm) from the initial line towards the end of the sleeve and mark this spot. This will be the cutting line for the new sleeve length.

By trying on the jacket and carefully measuring and marking the new sleeve length, you can ensure a more precise alteration that results in a well-fitted and tailored jacket.

Mark the sleeves where you want them to end

Marking the spot where you want the sleeves to end is crucial to getting the desired fit. Try on the jacket and identify the ideal sleeve length. It's a good idea to bend your arms and hold them in various positions to determine the most comfortable length. Once you've found the spot, you can make a few chalk marks around the sleeve to indicate the desired length. Remove the jacket and connect these marks into a solid line going around the sleeve. This line will serve as a guide for the new sleeve length.

To ensure a straight and consistent line, use a ruler to connect the marks. This step is important to achieve an even and symmetrical sleeve length. It is also a good idea to measure the distance from the end of the sleeve to ensure that all the marks are the same distance from the edge. This will help you achieve a neat and professional finish.

When marking the sleeves, consider leaving some extra fabric. For example, you might want to leave 0.5 cm or 1 cm of fabric below your wrist to account for different arm positions. This extra fabric will ensure that the sleeves are not too short when you bend your elbows. It is always better to have a little extra fabric that can be folded or hidden, rather than sleeves that are too short.

Additionally, consider the seam allowance when marking the sleeves. The seam allowance refers to the extra fabric needed to create a neat seam when hemming the sleeves. Typically, you will need to leave around 2 inches (5.1 cm) of fabric below the desired sleeve length for the seam allowance. This extra fabric will be used when hemming the sleeves and will ensure a neat and secure finish.

Measure 2 inches from the marks

Now that you have marked the sleeves of your sport coat where you want them to end, it's time to measure 2 inches (5.1 cm) from these marks. This step is crucial as it allows for a seam allowance, ensuring you don't cut the sleeves too short. It also leaves room for future length adjustments if needed.

Using a measuring tape, measure 2 inches (5.1 cm) down from the marks you just made. Make several chalk marks at this new spot, all around the sleeve. This will be your cutting line, so it's important to make sure the marks are consistent and straight. You can use a ruler to help guide you in making a straight line.

Once you have marked the new cutting line, connect the marks to create a solid line. This line should be parallel to the first line you drew and 2 inches (5.1 cm) below it. This technique ensures that your sleeves will be shortened evenly all around.

At this stage, you may want to put the sport coat back on to double-check that the new length is comfortable and where you want it. Make any necessary adjustments to the marks before proceeding. Remember, it's always better to err on the side of caution and leave the sleeves a little longer, as you can easily trim off a little more, but you can't add length back once it's cut.

Now that you have carefully measured, marked, and double-checked the new sleeve length, you are ready to move on to the next step of shortening your sport coat sleeves.

Cut the outer fabric along the second line

Now that you have prepared the sport coat sleeve for shortening, it is time to cut the fabric. This step is crucial, as it will determine the new length of the sleeve. Before you begin, ensure that you have marked the second line clearly all the way around the sleeve. This line should be 2 inches (5.1 cm) from the first line, which indicates your desired final sleeve length.

When you are ready, take your sharp scissors and begin cutting along the second line. Cut slowly and carefully, ensuring that you are only cutting through the outer sleeve fabric. It is important to be precise and follow the line as closely as possible. Take your time with this step, as any mistakes could affect the final look of your sport coat. Remember to cut both sleeves, following the same process for each.

As you cut, be mindful not to cut through the lining fabric. The lining should have been moved up and out of the way before starting this step. If necessary, you can pin the lining in place to ensure it stays clear of the scissors. It is also a good idea to press the pieces of the sleeves beforehand to ensure you are working with nice, clean edges.

Once you have finished cutting, you should have a clear view of the raw edges of the outer sleeve fabric along the second line. The next step will be to pull the lining fabric back down, ready for hemming.

Remember, it is always better to cut less fabric than necessary and then trim more later, rather than cutting too much fabric at once. You can always cut more fabric if needed, but you cannot add fabric back once it has been cut.

Hem the sleeves

Now that the sleeves have been cut, it's time to hem them. Start by pulling the lining fabric back down so that it extends past the new end of the sleeve fabric. If you used pins to hold the fabric back, remember to remove them first.

The next step is to trim the jacket lining. It should be slightly longer than the finished sleeve—around an inch longer to be precise. This is to prevent the sleeve from crumpling when you move around. If you cut the lining to the exact same length as the sleeve, it will cause the sleeve to pucker and look unsightly.

Now, fold the fabric under by 5 centimetres (2.0 in) so that it covers the lining. Ensure that the jacket lining and outer material are aligned, then fold the outer material at the end of the sleeve over the lining fabric towards the inside of the sleeve. This will neatly hide the raw edges of the lining and outer material.

Place a few pins around the folded sleeve to keep it in place. Insert the pins perpendicular to the end of the sleeve so they will be easier to remove as you sew. Place a pin about every 5 cm (2.0 in).

Now, it's time to sew. Set your sewing machine to the straight stitch setting and sew all the way around the edges of the sleeve. Make sure to use a thread that matches the colour of the jacket, such as black thread for a black jacket. Position the stitch about 3 cm (1.2 in) from the folded edge. Remember to remove the pins before you sew over each area to avoid damaging your machine.

If you prefer, you can also sew the sleeve by hand. When you reach the end, backstitch by 5 cm (2.0 in) to secure the final stitches. To do this, press down on the lever on the side of your sewing machine and hold it while still applying gentle pressure to the pedal. This will reverse the direction of your sewing machine. Sew for 5 cm (2.0 in) and then release the lever and sew back to where you started. Finally, trim off the excess threads. Repeat the same process for the second sleeve, and you're done!
